Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a radio telephone device, and more particularly to a radio telephone device in which a mobile station has separate off-fuckswitches and on-fuckswitches.

Generally, a mobile station of a radio telephone device has one hook switch, and when the handset is placed in the base set, the hook switch is turned off and placed in an on-hook state, and when the handset is picked up, the hook switch is turned on and placed in an off-hook state. Become.
There is also a device that uses a slide switch to turn the hook into an on-hook or off-hook state depending on the state of the slide switch.

In recent years, some mobile stations have separate off-box and on-box switches.

[Conventional technology]

Conventionally, in this type of wireless telephone device in which a mobile station has an off-hookswitch and an on-hookswitch, the mobile station switches off-hooks when the off-hooks switch is pressed, regardless of whether the mobile station is making a call or is in a conversation state. The signal is sent for a predetermined time, and when the on-hook switch is pressed, the on-hook signal is sent for a predetermined time, and then a call-end signal is sent. When the base station receives the off-hook signal, the line relay is turned on, and the on-hook signal and When the end signal is received, the line relay is turned off. That is, pressing the off-hook switch brings the device into an off-hook state, and pressing the on-hook switch brings it into an on-hook state.

[Problem that the invention seeks to solve]

However, with the above configuration, when you operate the hook to receive a service such as a telephone, you must press the on-hooks switch to stay on-hooks for a predetermined period of time (for example, 0.5 seconds to 1 second). It is necessary to press the off-hook switch after a predetermined period of time, which has the drawback that the off-hook operation becomes complicated.

[Means for solving problems]

A wireless telephone device to which the present invention is applied includes a base station connected to a wired telephone line and a mobile station that can be wirelessly connected to the base station, and the mobile station has an on-box switch and an off-box switch. and a means for wirelessly transmitting to the base station, the base station having a means for receiving a signal wirelessly transmitted from the mobile station, and a line relay for connecting or disconnecting the wired telephone line. has.

According to a first aspect of the present invention, the mobile station:
The base station includes a transmission signal control means for transmitting an off-hook signal to the wireless transmission means when the off-hook switch is pressed at the time of making a call or during a conversation, and when the base station receives the off-hook signal at the time of making a call, The line relay control unit is connected to the line relay, and when an off-hook signal is received during a call, the line relay is turned off while the off-hook signal is being received.

According to a second aspect of the present invention, the mobile station:
The base station includes a transmission signal control means for transmitting an off-hook signal to the wireless transmission means when the off-hook switch is pressed during a call and an on-hook signal when the off-hook switch is pressed during a call, and the base station includes: When an off-hook signal is received during a call, the line relay is connected, and when an on-hook signal is received during a call, the line relay control section is configured to disconnect the line relay while the on-hook signal is being received. have.

[Effect]

According to the first aspect, when the mobile station presses the off-hook switch when making a call, it sends an off-hook signal to the base station for a predetermined period of time, and when the mobile station presses the off-hook switch during a call, it sends an off-hook signal to the base station only while the off-hook switch is pressed. When the base station receives an off-hook signal at the time of a call, it connects the line relay to put it in a talking state (off-hook state), and when it receives an off-hook signal in the talking state, it turns off the line relay only while receiving the off-hook signal. It can be set as “discontinued”.

According to the second aspect, the mobile station transmits an off-hook signal for a predetermined period of time when the off-hook switch is pressed during a call, and when the off-hook switch is pressed during a call, it transmits an on-hook signal only while the off-hook switch is pressed. When pressed, an on-hook signal is sent for a certain period of time, and then a call-end signal is sent out. When the base station receives an off-hook signal, it connects the line relay and puts it into a path state, and when it receives an on-hook signal in the call state, the base station receives the on-hook signal. The line relay can be "off" only while the call is on, and the line relay can be "off" when an on-hook signal and a call termination signal are received.

Therefore, the hooking operation is extremely simple, just by pressing the off-hook signal.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

The drawing is a block diagram showing the configuration of an embodiment of the wireless telephone device according to the present invention, and only the parts related to the present invention are shown in the figure. In the figure, 1 is a mobile station, which includes a transmitter 11, a signal generator 12, and a controller 1.
3, it has an off-foot switch 14 and an on-foot switch 15. 2 is a base station, receiving section 2
1. Comprising a signal detection section 22, a control section 23, a hybrid circuit 24, and a line relay 25; 3.
is a telephone line, 4 is a transmitting antenna, and 5 is a receiving antenna.

Control unit 13 of mobile station 1 and control unit 2 of base station 2
There are a first embodiment and a second practical example, which will be described below, depending on the difference in the control operations.

(First Embodiment) The control section 13 of the mobile station 1 has a state storage section (not shown) that stores whether or not the mobile station is in a talking state (off-hook state). When the off-hook switch 14 is pressed while this state storage section indicates the "common talk state," the control section 13 causes the signal generation section 1
2 to generate an off-hook signal for a certain period of time, and sets the state storage section to the "talking state". Further, if the off-hook switch 14 is pressed while the state storage section indicates the "talking state," the control section 13 sends an off-hook signal to the signal generation section 12 while the off-hook switch 14 is pressed. Instruct it to occur. Furthermore, if the on-hook switch 15 is pressed while the status storage section indicates the "call state," the control section 13 causes the signal generation section 12 to generate an on-hook signal for a certain period of time, and then sends a call-end signal. , and sets the state storage section to the "non-call state".

On the other hand, the control unit 23 of the base station 2 also has a status storage unit (not shown) that stores whether or not the base station 2 is in a call state. When the signal detection unit 22 detects an off-hook signal while the status storage unit indicates the “non-call state”, the control unit 23 controls the line relay 25
is set to "connected" and the state storage unit is set to "talking state". Further, if the signal detection unit 22 detects an off-hook signal while this state storage unit indicates the “talking state”, the control unit 23 “cuts off” the line relay 25 while the off-hook signal is detected.
shall be. Furthermore, if the signal detection unit 22 detects an on-hook signal and a call end signal while this status storage unit indicates the “call status,” the control unit 23 turns off the line relay 25 and stores the status memory. set the unit to “non-call state”.

Next, the operation of the first embodiment will be explained with reference to the drawings.

As an initial state, a "non-calling state" is set in the control unit 13 of the mobile station 1 and the status storage units of the base station 2 and the control unit 23, and the wireless telephone device is assumed to be in a non-calling state.

In this state, when the mobile station 1 makes a call, when the off-hook switch 14 is pressed, the control unit 1
3, the control section 13 activates the signal generation section 12 to generate an off-hook signal for a certain period of time, and sets the state storage section to the "talking state". The transmitting section 11 modulates a carrier wave with the off-hook signal generated from the signal generating section 12, and this modulated wave is sent out from the transmitting antenna 4. In the base station 2 , the modulated wave received by the receiving antenna 5 is demodulated by the receiving section 21 and input to the signal detecting section 22 . When the off-hook signal is detected by the signal detection section 22, the control section 23 turns the line relay 25 "on" based on the detected off-hook signal, connects the hybrid circuit 24 to the telephone line 3, and establishes a talking state. , set the status storage section to "talking status".

If you want to perform a hooking operation on the mobile station 1 during this call, press the off-foot switch 14 to
The control section 13 detects this and controls the signal generating section 12 to generate an off-hook signal while the off-hook switch 14 is pressed. The transmitter 1 receives an off-hook signal generated from the signal generator 12.
1 modulates a carrier wave, and this modulated wave is sent out from a transmitting antenna 4. At this time, in the base station 2, the modulated wave received by the receiving antenna 5 is demodulated by the receiving section 21 and input to the signal detecting section 22. When the off-hook signal is detected by the signal detection section 22, the control section 23 turns off the line relay 25 only while the off-hook signal is detected, and when the off-hook signal is no longer detected, the control section 23 turns off the line relay 25.
Then, the call status is resumed.

To end a call, when the on-hook switch 15 is pressed on the mobile station 1, the control unit 13 detects this, starts the signal generator 12, generates an on-hook signal for a certain period of time, and then generates a call-end signal. ,
Set the state storage unit to "non-call state". The transmitting section 11 modulates a carrier wave using the on-hook signal and the end-of-call signal generated from the signal generating section 12, and this modulated wave is transmitted from the transmitting antenna 4. In the base station 2 , the modulated wave received by the receiving antenna 5 is demodulated by the receiving section 21 and input to the signal detecting section 22 . When the signal detection unit 22 detects the on-hook signal and the end-of-call signal, the control unit 23 disconnects the line relay 25 to disconnect from the telephone line 3, brings it into the receiving state, ends the call, and stores the state. set to “non-call state”.

(Second Embodiment) In this example, the control section 13 of the mobile station 1 has a state storage section that stores whether or not it is in a call state. The difference from the first embodiment is that when the off-hook switch 14 is pressed while this state storage section indicates the "talking state", the control section 13 causes the off-hook switch 14 to be activated for the signal generation section 12. Instructs to generate an on-hook signal while being pressed.

Further, the control section 23 of the base station 2 also has a state storage section that stores whether or not the base station is in a call state, as in the first embodiment. The difference from the first embodiment is that when the signal detecting section 22 detects an on-hook signal while this state storage section indicates the "talking state," the control section 23 detects the on-hook signal. The interline relay 25 is turned off.

Next, the operation of the second embodiment will be explained with reference to the drawings. However, in this embodiment, since the operations for making and ending a call are the same as those in the first embodiment, only the operation for the hooking operation during a call will be described.

When performing a hooking operation on the mobile station 1 during a call, when the off-foot switch 14 is pressed, the control section 13 detects this and switches the off-foot switch 1.
The signal generator 12 is controlled to generate an on-hook signal while 4 is pressed. Signal generator 12
The transmitting section 11 modulates a carrier wave using the on-hook signal generated by the transmitter, and this modulated wave is transmitted from the transmitting antenna 4. At this time, in the base station 2, the modulated wave received by the receiving antenna 5 is demodulated by the receiving section 21 and input to the signal detecting section 22. When the signal detection section 22 detects an on-hook signal, the control section 2
3, the line relay 25 is "off" only while the on-hook signal is detected, and when the on-hook signal is no longer detected, the line relay 25 is "on" to resume the talking state.

〔Effect of the invention〕

As explained above, according to the present invention, there is an advantage that the hooking operation on the radio telephone device can be performed easily and at any timing.
